CARBONATOR.

Application filed December 5, 1923. Serial No. 678,576.

pump to raise the pressure of the incoming water above the normal working pressure of the gas in the carbonatin chamber. apparatuses of this. kin of which I am aware, it has been necessary to deliver the incoming water at considerable pressure,

such pressure being applied to the operating of the control mechanism. Therefore, while apparatuses of this kind have been useful in places where water under pressure is available as, for-example, in cities having 'a water works system, difliculty has often been experienced where it was necessary to draw the supply of water from a storage tank or other source which afforded only a low head or pressure on the water delivered therefrom. v

The object of the present invention is to produce a simpleiand novel apparatus of the character described, .which does not depend upon the pressure of the incoming water for its operation and will therefore work successfully and efliciently wherever thereis a suflicient head of water to enable the water to fiow by gravity to the apparatus.-

The various features of novelty whereby my invention is characterized will hereinafter be pointed out with particularity in the claims; but for a full understanding of my invention and of itsobjects and advantages, reference may' be had to the following detailed description taken'in connection withthe accompanying drawing, where- Figure 1 is a view partly in side-elevation and partly in. vertical section through an apparatus arranged in accordance with the preferred form of my invention; Fig. 2 is a top plan view of the -apparatus; Fig. 3 is a vertical section, on an enlarged scale, through the supporting means for the float and the elements directly actuated by the float; Fig. 4 is a detail onan enlarged scale showing a fragment of thecontrolling lever and trigger, and two of the four main valves, the latter being'in section rin the same positions as in Fig. 1; Fig.5 is a vertical section through the two valves that appear directly behind the valves in Fig. 4E and are controlled by the same lever that controls In all the latter valves; 6- is a view similar to Fig. 4, showing the parts in the posi .tions which they assume when the carbonating chamber is empty; Fig. 7 is a view similar to Fig. 5, showin the valves inthe positions that correspon to the position shown in Fig. 6; Fig. 8 is a view similar to Figs. 4 and 6, showing the positions of the parts corresponding to a high liquid level in the carbonating chamber; Fig. 9 is a view similar to Figs. 5 and 7, the valves being in positions corresponding to the positions of the valves in Fig. 8; Fig. 10 is a view on an enlarged scale, looking at the right hand side of Fig. 1, only the trigger and its support being shown: and Fig. 11 is a section taken approximately on line 1111 of Fig. 10 showing, inaddition to what appears in Fig. 10 a fragment of the wall of the carbonating chamber, and a part of the float.

Referring to the drawings, 1 represents a. sealed container of any. usual or suitable size and shape, to which I shall refer as the carbonating chamber. Water or other liquid is delivered into this chamber through a pipe'2 extending downwardly through the top thereof, preferably at an angle to the vertical. The carbonating gas is delivered into the bottom of the chamber through a connection 3 betweenthe bottom of the chamber and a pipe 4. The charged liquid is dispensed through a pipe 5 opening out of the chamber nearthe bottom thereof and leading to a suitable draught arm or other dispensing device, not shown. As the gas entersthe bottom of the chamber it may be caused to carbonate the water in the chamber in a suitable way, the. present invention having nothing to do with this detail. In the usual devicesof this kind some of the gas passes up through the water and is collected in the top of the chamber, the pressure of this pocketed gas serving as means to force the liquid throughthe dispensing outlet when the latteris open.

In order that the apparatus may function efliciently in accordance with the purpose of I this invention, it is necessary that whenever also necessary that whenevr' -the water in the chamber hasrisen to a predetermined level, the water inlet. will be closed and the pipe for delivering the carbonating gas be placed in open communication with the source of supply of gas. It is also desirable,

in order to prevent waste of gas, that the supply of gas be shut oii before the water has been completely emptied out of the chamher, because the pressure of the gas stored in the chamber will be sufficient for dispensing purposes even though no more gas be admitted into the chamber after the level of the water has dropped about two thirds. of the distance from its highest point. All of the operations must be performed automatically and .positively so as to insure against failure at any time.

All of the valve mechanism is controlled byamain controlling lever 6 arranged above the carbonating chamber and adapted to swing about a horizontal pivot 7. On one end of this leveris hung a heavy weight 8. while'on the other end is hung what I shall term a bucket 9 closed both at the bottom and at the top, the relative masses of the empty bucket and the weight 8, and the rela- 'tive proportions of the lever arms beingsuch that the lever will be swung in the clockwise direction by the weight 8 when the bucket is 7 stantly to hold it against its seat.

empty and the lever is free to swing; while, when the bucket is full of water, the lever will be swung'in. the counter-clockwise direction by the bucket when the lever is not otherwise restrained. The bucket is adapted to be filled with water from the carbonating chamber,"=" under certain conditions,

through a fiexible'conduit 10 leading from the bottom of the bucket to and communicating with the interior of the carbonating chamber at a point 11 slightly below the lower end of the water pipe 2. There is a second flexible conduit 12 extending from the top of the bucket to the valve mechanism for the purpose, as will hereinafter beexplained,

of placing the top of the bucket and the top of the chamber in communication with each other.

The 'valve mechanism consists of four valves, shown in detail in Figs. 4 and 5 and also in Figs; 7 to 9. For the sake of simtion between the two compartments of each valve chamber is determined by four upwardly-seatin valves 19, 20, 21'and 22. Beneath each va ve is a spring 23 tending con- Each valve is provided with a stem 24 extending upwardly from the same through the top-of the valve casing. The valves may all be exactly alike and, for the sake of cheapness of manufacture and interchangeability in use, are preferably made so. The lever 6 is widened at the middle, as best shown in t Fig. 2, so that portions thereof lie directly above all four of the valve stems. The pivotal axis of the lever lies midway between the two pairs of valve stems, that is, between the front and rear stems on one side and the front and rear stems on the other side. The parts are so proportioned that when the lever is horizontal it is out of engagement with all of the stems except that connected to valve 21, thus permitting all of the valves except the valve 21 to close; whereas, when the lever is swung in-one direction it engages one pair of valve stems and forces the corresponding valves open and, when it is swung in the other direction, it engages the other pair of stems and forces the other two valves open.

The lower compartment of the valve chamber 15 communicates with a supply pipe 26 leading from a suitable source of compressed gas, not shown; whereas the upper compartment of this same valve chamber. is connected with the upper end of the pipe 4. It will thus be seen that whenever the valve 19 is open,'the bottom of the car- -municates with a water main 27. It will be seen that when'the valve '20 is open, water may flow from the main 27 into the top of the carbonating chamber, the flow being stopped, however, when the valve is closed. Thev lower compartment of the valve chamber .17 which lies directly behind the chamber 15 communicates withthe top of the car bonating chamber through a nipple 28. The

upper compartment of this same valve chamber is-in open communication with the flexible conduit 12 leading from the top of the bucket. VVhenever'the valve 21' is open, the top of the c'arbonating chamberis placed in direct communication with the top of the bucket, this communication being shut off when the valve 21 is closed. The fourth valve chamber 18, lying directly behind the chamber 16, has a vent 29 leading to atmosphere from the upper compartment therein. The lower compartment of this valve chamber is connected to the upper compartment of the chamber 17 by a conduit 30, best shown in Fig. 2 and in (btted lines in Figs. 5, 7 and 9. Wheneverv the valve 22 is open,

lllii lit) the top of the bucket is vented to atmoswhenever the top of the carbonating chamher is in communication with the upper compartment of the valve chamber 17, by reason of the valve 21 being open and thus placing the interior of the carbonating chamber in communication with the lower compartment of the valve chamber 18, venting to atmosphere will be prevented because the valve 22 must at this time be closed.

trolled by a float 321 arranged in the carbonating chamber. This trigger cooperates with several shoulders on the lever so as to serveto lock the lever in its various positions against the tendency of the weight or the bucket to move it, until the proper conditions, have been brought about. In the arrangement shown, the actuating lever has a depending arm 32 arrangedat a short distance inward from the end on which the weight is hung. On the lower end of the arm is an upwardly-facing shoulder 33 lying outwardly of the arm. 'At some distance above this shoulder is a downwardly facing shoulder 34. Still farther up is a second downwardly facing shoulder 35 lying outwardly of a vertical plane through the outermost point of the shoulder 34. At the extreme upper end of the arm is an inwardly-directed .notch 36 having a downwardly and outwardly sloping lower wall 37, at theextreme' lower and outer end-of.

which there may be placed a roller 37 or other anti-friction-member; this notch extending inwardly at least as far and prefer- I ably fartherthan the vertical plane passing through the inner boundary of the downwardly facing shgulder 34. The trigger has at 1ts upper end an inwardly-directed finger 38, flat at. the top. The lower edge of the finger is formed of a downwardly and outwardly inclined face 39 having approximately the same angle as the face. 37 on the lever, together with a shortrupwardly directed' face 40 adjacent to the stem of the trigger; this latter face constituting a hook.

The trigger is controlled primarily by the float. As best shown in Figs. 1, a, 10 and 11, the float is fixed on one end of a rod or arm 41 that is pivotally' supported, as indicated at 42, in a jaw 43 fixed to the wall of the'carbonating chamber and lying in approximately the same vertical plane as the main actuating lever. The jaw is carried on one end of a stem 44 passing through the wall of the carbonating chamber, the jaw forming what may be termed a head for the stem. The outer end of the stemis externally screwthreaded and is provided with terior 0f the thimble.

a nut 45 that enga es with a suitable cupbetween which and theshaped washer 46, 7 wall of the carbonatin chamber lies a'suit able packing material 4 1 A packing washer may be placed betweep the head and the chamber by, an airtight and watertight joint.

That o'rtion of thestem that lies within the th ckness of the wall of the carbonator is preferably made square, as indicated at 491 in Fig. 1, and fits a square hole in said The actuating lever for the valves is con-' trolled by a trigger 31 which is in turn conwall, to prevent the stem from turning. The stem 44 is made tubular but has between the ends thereof a: transverse partition 49.

Within the chamber on the inner side .of the partition is a slidingoblock formed with an inwardly-directed jaw 51 containing ananti-friction roller 52. The innerend of the float-supporting arm or rod is in the form ofa comparatively thin vertical plate 53 entered-into the jaw in the block 50 and having a cam edge 54 engaged with the roller 52. On the outer end ofthe stem 44 is screwed an elongated. thimble 56 1 within which lies a piston-like follower 57. This follower lies at the inner end of the thimble, and between the same and the outer end of the thimbla is placed a strong spring 58 which tends constantly to force the follower of the stem 44, passes through the partition 49 so as to engage at its inner end with the block 5Q and at its outer end with the middle of the follower 57. A plug 60 is screwed into the extreme outer endof the stem, and arranged between thislplug and the transverse" partition is a suitable packing 61 which will prevent Water.or';gas1- from escaping through the stem pastthe' rod 59.

The cam is so shaped that when the float is in its highest position, the block will be at the outer limit of its movement, the spring 58 being held under compression by the follower, whereas, when thefioat' is in its lowermost position, the block will have been pushed inwardly by the action of the spring '58 which has expanded and forced the follower back against the rod 59.

The follower 57 has attached to it a rod inwardly. A small rod 59, arranged axially or shank 62 that extends axially of the thimble, in the outward direction, to theexand extend into proximity tothe carbonating chamber where they arepivotally con-- nected to the two arms 64 at the lower forked end of the trigger 31, the trigger being pivotally supported, as indicated at 65, on a lug 66 attached to or forming part of the wall of th carbonating chamber. The

parts are so proportioned that the trigger may swing about its pivot in the vertical plane containing the main actuating lever 6. Outward movements of the lower end of the trigger are limited by shoulders or nuts 67 on the rod or shank 62, while inward movements are permitted independently of this rod or shank against the resistance of a spring 68 surrounding the rod or shank within the thimble, hearing at one end on the follower 57 and at the other end against a follower that bears against the inner face of the U-shaped yoke. This second follower may conveniently be in the form of two members' 69 and 70 screw-threaded together so that the effective length of this follower may be varied, and slidable in the end wall of the thimble.

0pemtz'0n.In describing the operation of my improved apparatus the cycle may be assumed to begin when the conditions are those illustrated in Fig. 1, namely, when the carbonating chamber remains about one third full of water during the process of emptying it; the water being indicated at A. The actuating lever for the valves is now in its horizontal position, so that all of the valves except valve 21 are closed. The water which .was contained in the bucket at one time has been emptied into the carbonating chamber, so that the weight 8 tends to swing the lever in the clockwise direction, as viewed in Fig. 1.

No water or gas .can enter, and therefore the water that is drawn off and dispensed is forced out of the carbonating chamber by reason of the gas under pressure'that is stored in the chamber above the charged water. As the water is dispensed, the liquid level in the carbonating chamber falls and therefore the float also falls and permits the spring 58 gradually to force the follower 57 inwardly, and thus draw inwardly the U-shaped yoke connected to the lower end of the trigger. The trigger at this time is enga edwith the shoulder 35 -on the actuating ever but, as the yoke is gradually drawn in, th'e'upper end of the trigger 1s gradually moved outward until it clears the shoulder 35; and therefore removes the support for. the actuating lever while the valve 19 remains closed and valve 21 closes. The-reason for leaving the valve 21 slightly openwhen the parts are in the positions'shown in Fig. 1, is to permit any small quantity of water that may have'rev mained in' the bucket to drain intothe car- 'bonating chamber through the'fiexibleconnection 10 while the bucket remains in the pos1t1on shown m Fig. 1. -Consequently the I gravity into the carbonating chamber.

gas can flow freely from the carbonating chamber through the'flexible conduit 10 and duit 30, andthroughthe valve chamber 18,

as can best be seen in Fig. 7 Consequently the pressure in the carbonating chamber will be released until the pressure drops to that of atmosphere. The water valve 20 is now open, as shown in Fig. 6 and, since the pressure in the c'arbonating chamber is only equal to atmosphere, water will flow by As the water rises, the gas above the same will be forced out through the flexible connection 10 and the bucket to atmosphere, so that the incoming water meets with no resistance until it rises above the outlet end of the inclined water pipe 2. As soon as the water rises sufliciently high to cover theoutlet end of the pipe 2, the gas remaining in the chamber above the water will be compressed to an extent depending'upon the head of the incoming water. In order to insure that the water will flow successfully, there must be a slight head, even though it be. due only to the employment of a storage tank lying a spring 68; because the top of the bucket is still venting to atmosphere, whereas the gas space in the top of the carbonating chamber is shut off. from atmosphere and pressure is being built up therein.

During the time that the carbonating chamber is filling with water, the float is I gradually rising, causing the trigger to be swung in the counter-clockwise direction, as viewed in Fig. 1 and Fig. 6, the actuating force being supplied from the follower 57 through the inner spring'68 and the secondary followermade up of the parts 69'and 70, so that the trigger will have been pressed laterally far enough to cause the finger to enter the notch 36; When the water reached such a level in the bucket 9 as to cause the bucket to begin to overbalance the weight 8,

the lever began to swing in the counterclockwise direction, but its movement was checked through the engagement of the in:

clined face 37 on the lever with the inclined face 39 on the'trigger. The inclined faces of the lever and the trigger, respectively,

are held together by-the force of the spring- 68 and, when the weight of the water in the bucket becomes sufliciently great, the resistance of the spring 68 will be overcome and the trigger end of the lever will rise, at the same time forcing the trigger out of the way by a wedging action. The resistance of the spring is slowly overcome but, when the inclined face 39 on the trigger comes in contact with the anti-friction roller 37*, the re sistance is uickly overcome and the trigger end of the lever rises with a snap action until its movement is arrested by the engagement of the shoulder 33 with the hook or downwardly-facing shoulder 40 on the trigger. During all this time the supply of gas has been shut ed and the water valve has remained open. When the lever has completed its swinging movement in the direction under consideration, namely, slightly beyond the position shown in Fig. 8, the valves 20 and 22 are closed-and the valves 19 and 21 are open,'as shown in Figs. Sand 9. Consequently, the supply of water is shut ofl and the vent tovatmosphere is closed. At

the same time, the gas valve 19, being opened, permits gas to flow into the bottom of the carbonator. Another result is that the valve 21 being opened, communication is established between the gas space in the top of the carbonating chamber and'the top of the bucket, through the flexible conduit 12.

The angular movements of the actuating le-- ver are not very great and therefore,when the bucket, filled with water, is in its lowermost position, the level of the water therein is still above that in the carbonating chamber but, as soon as the top of the carbonating chamv her is placed in open communication with the top of the bucket, water will flow from the bucket into the carbonating chamber until the level is the same in each. The partially emptied bucket therefore becomes too light to hold its end of the lever down and therefore the weight 8Vswingsthe lever in the direction to raise the bucket. However, it is necessary that the gas valve remain open during the time that the greater part the charged water-is being dispensed, and

therefore the lever must not be permitted to assume a horizontal position until it ist'ime for the gas to be shut ofi. The trigger is still being pressed against the depending arm of the lever and therefore, as the trigger end of the lever starts to drop, the shoulder 34: will strike the upper end of the trig er as shown in Fig. 8, thereby arresting furt e1 downward movementof the lever until the trigger has been released. The gas valve 19 and the valve for controlling communication" between the tops of the carbonator chamber and the bucket, respectively, therefore remain open until the trigger is released to permit the lever to swing from its position shown in Fig.8 to that shown in Fig. 4

whereupon the valve 19 closes while the other:

' pressed to the highest degree of compr 21, remains open. When the parts first are brought into the position shown in Fig. 8, the float is'at the extreme upper limit of its movement and the two springs are 633m- 1011 to which'they are. subjected during the operation of the. apparatus. Consequently, as the float drops, due to the withdrawal of water for dispensing the same, the triggerwill remain in engagement with the shoulder 34 until the cam associated with the float is moved to a position which permits the spring 58 to swing the trigger out of engagement with said shoulder. The cam is so proportioned that this occurs "only when the water in the carbonatingchamber has fallen to such a level that it will be unnecessary to introduce more gas into the. said chamber, namely, when the chamber has been emptied to about the point indicated in Fig. 1. When this condition is reached, the end of the lever shown in Fig. 8 drops down but, because the shoulder 35' is arranged out- Wardly beyond the shoulder'34, the downward movement of the lever is arrested when the shoulder 35 strikes the upper end of thetrigger, as shown in Fig. 4;; all of'the valves except valve 21 being closed,.and the water being thereafter dispensed under the pressure already in the 'carbonating chamber, as heretofore explained. v

The cycle of operations will be repeated automatically as liquid is drawn from the carbonating chamber, so that the latter will become automatically filled and the water be automatically charged without undue waste of charging gas, and without regardto the ressui'e of the water at the source of supp y, so long as the source is such as to afford a slight head which will cause the water to flow freely when the water valve is opened.

.If desired, the float-supporting arm 41 may have shoulders 7 0 fo med in the vicinity ofthe supporting jaw 43, for engagement with the jaw at the upper and lower limits of movement of the float.

It will thus be seen that I have produced a simple and novel liquidnharging apparatus which will operate automatically, with a minimum wasteof charging gas, without the use of amotorand wit'hout requiring any greater pressure-on'the incoming water than is necessary to cause the water to flow freely by gravity into the charging apparatus.
